移植树木时,过去一般常用稻草将树根包扎起来。这样做,根部和泥土中的水分易被稻草吸收、蒸发,使树根干燥,移植后稻草又不易腐烂,树根难以伸展,影响树木的健康生长及成活,包扎树根又费工费时,还不便于运输。前不久,日本加濑青发明了药液裸根移植法;把聚乙烯醇搅拌成适当粘度的液体,然后用喷雾器喷洒到树木根部及其所带起的泥土表面上,使之自然硬化,形成被膜层后就可装载移植了。
When transplanting trees, the straw was used to wrap the roots of trees in the past. In doing so, the water in the roots and the soil is easily absorbed by the straw, evaporates, the roots are dried, the straw is not perishable after transplantation, the roots are hard to stretch, affecting the healthy growth and survival of the trees, Not easy to transport. Not long ago, Japan Kase green invented the botanical bare root transplantation; the polyvinyl alcohol stirred into a suitable viscosity of the liquid, and then spray to the tree roots and the soil it brought the surface, so that the natural hardening, the formation of After the film can be loaded transplant.
